<virtual/>

Attribute	Type	Description
enabled	Boolean	Enables or disables the configuration.
item-height	Double	Specifies the height of the virtual item. All items in the virtualized list must have the same height. If the developer does not specify one, the framework will automatically set itemHeight based on the current theme and font size.
map-value-to	String	The changes introduced with the Kendo UI R3 2016 release enable you to determine if the valueMapper must resolve a value to an index or a value to a dataItem. This is configured through the mapValueTo option that accepts two possible values - "index" or "dataItem". By default, the mapValueTo is set to "index", which does not affect the current behavior of the virtualization process.For more information, refer to the article on virtualization.
value-mapper	String	The component calls the `valueMapper` function when the component receives a value, that is not fetched from the remote server yet. The component will pass the selected value(s) into the `valueMapper` function. In turn, the valueMapper implementation should return the respective data item(s) index/indices as specified via the `map-value-to` configuration. As of the Kendo UI R3 2016 release, the implementation of the `valueMapper` function is optional. It is required only if the widget contains an initial value or if the `value` method is used
